Abstract

We study how the production of the neutron-rich magnesium isotopes in intermediate mass Asymptotic Giant Branch stars is affected by uncertainties in the neutron-capture reactions involving the Mg isotopes and uncertainties in the Ne-22 + alpha-capture reaction rates. We also examine how uncertainties in these rates affect the stellar yields of species from Ne-22 through to P-31, which is important for chemical evolution models.
